ERROR SIGNAL HANDLING UNIT, DEVICE AND METHOD FOR OUTPUTTING AN ERROR CONDITION SIGNAL
First Claim
1. An error signal handling unit, comprising:
- an error handler configured to receive an error signal indicating an error condition;
wherein the error handler is further configured to receive a recovery signal indicating a mitigation of the error condition or indicating that a mitigation of the error condition is possible; and
wherein the error handler is further configured to output an error condition signal based on the error signal in response to a reception of the error signal if within a given delay time from the reception of the error signal, the error handler does not receive the recovery signal, and otherwise omit outputting the error condition signal.

Abstract
An error signal handling unit includes an error handler configured to receive an error signal indicating an error condition. The error handler is further configured to receive a recovery signal indicating a mitigation of the error condition or indicating that a mitigation of the error condition is possible. Furthermore, the error handler is further configured to output an error condition signal based on the error signal in response to a reception of the error signal if within a given delay time from the reception of the error signal, the error handler does not receive the recovery signal, and otherwise omit outputting the error condition signal.

29. An error signal handling unit comprising:
-
a first input terminal; a second input terminal; an output terminal; and an error signal delay stage coupled between the first input terminal, the second input terminal and the output terminal; wherein the error signal delay stage is configured to provide, in response to a reception of an error signal from an external device at the first input terminal indicating an error condition in the external device, an error condition signal based on the error signal at the output terminal if within a given delay time, the error signal delay stage does not receive a recovery signal from the external device at the second input terminal indicating a mitigation of the error condition in the external device or indicating that a mitigation of the error condition in the external device is possible, and otherwise omit outputting the error condition signal.

30. A system, comprising:
-
means for outputting an error condition signal; means for receiving an error signal indicating an error condition; and means for receiving a recovery signal indicating a mitigation of the error condition or indicating that a mitigation of the error condition is possible, wherein the means for outputting the error condition signal is further configured to output an error condition signal based on the error signal in response to a reception of the error signal if within a given delay time from the reception of the error signal, the means does not receive the recovery signal and otherwise omit outputting the error condition signal.

31. An error signal handling unit, comprising:
-
an error signal decoding stage configured to receive an error signal indicating an error condition, decode the error signal, and generate a decoded error signal in response thereto; a recovery signal protocol detection stage configured to receive a recovery signal indicating a mitigation of the error condition or indicating that a mitigation of the error condition is possible, decode the recovery signal according to a given communication protocol decoding rule, and generate a decoded recovery signal; and an error condition signal generation stage configured to generate a fail safe mode request signal based on the decoded error signal, wherein the fail safe mode request signal indicates a request to an external device to enter a fail safe mode, and output the fail safe mode request signal as an error condition signal if within a given delay time from a reception of the decoded error signal, the error condition signal generation stage does not receive the decoded recovery signal, and otherwise omit outputting the fail safe mode request signal.
